Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The box may be of any preferred construction and as shown comprises a body 10 preferably of sheet metal and a plurality of rods 11 grouped about the exterior of the box to form protective means therefor. A cover 12 closes the top of the box and is connected thereto by means of spring hinges '13 which may be of any type and which normally hold the cover in open position when the lock is sprung so that merchandise maybe conveniently placed within the box or removed therefrom.

A keeper 14 is located upon the back of 6, 1924. Serial No. 736,312.

the box and a lock member 15;is slidable therein and is connected by means of a brace 16 to the cover'12 with the result that the cover and lock member move together. A latch 17 is mounted in the keeper 14 and is adapted to engage a notch in a side of the lock member 15 to secure the latter when the cover 12 is closed. A bar 18 disposed horizontally carries the latch 17 and is normally moved in one direction by means of the spring 19 which is mounted upon a reduced portion 20 of the bar and which is confined between elements 21 and 22, the latter being attached to the outer end of the reduced part 20 and the element v21 being let into an opening in a door jamb 23 or like part and to which is fitted an escutcheon 24.

WVhile the box is designed primarily for receiving milk bottles or jars, it is to be understood that it may be utilized for the safe delivery of bread or other merchandise which is usually delivered at a time when the members of a household are not up and about, thereby insuring the safe delivery and preventing the usual pilfering which is both annoying and expensive.
